Jailbreaking/unlocking is the process of removing the limitations imposed by smartphone manufacturers on devices running a mobile phone operating system (like Android, iOS, Symbian or Windows phone 7 OS) through use of custom kernels. Jailbreaking allows users to gain root access to the operating system, allowing users to download additional applications, extensions, and themes that are unavailable for users.

If you own a Samsung Windows Phone 7 device then you can unlock your phone. A developer, Jaxbot over at Windows Phone Hacker, released an interop unlock for WP7 devices. He name this file as WindowsBreak. To get root level access on your phone, you can either pay $99 and register with Microsoft via the developers hub, or there is the option to go for the newly-released Chevron, which costs $9. WP7 users who don’t have a Samsung will still have to resort to those methods, but the lucky Samsung users can get interop unlock for free, which grants a higher level of registry access than Chevron’s $9 developer unlock.

You don’t even need to be near a PC before you can use WindowsBreak. Here is the step-by-step guide to gain interop unlock on Samsung devices.
